Ultrasound biomicroscopy is a type of ultrasound eye exam that makes a more detailed image than regular ultrasound. High-energy sound waves are bounced off the inside of the eye and the echo patterns are shown on the screen of an ultrasound machine. This makes a picture called a sonogram.[1] It is useful in glaucoma, cysts and neoplasms of the eye, as well as the evaluation of trauma and foreign bodies of the eye.[1]
